Riverside Avenue Central Water Line Project
Limits: Railroad Tracks on the North to San Bernardino Ave on the South
Background Observations & Assumptions:
The existing 8”/10” mainline on Riverside Ave between the Railroad tracks on the North and San Bernardino Ave in the south was installed in the 1960s.
Barring a couple of leaks, there have not been major problems with the mainline to date. Based on discussions with the City, the only section of mainline pipe recommended to be replaced is the 8” ACP between the Railroad tracks to approx. South street.
Based on depths measured on the valve stem, it appears that the mainline is approx. 40” or greater deep throughout the section between the Railroad track and San Bernardino Avenue – so it appears the main line may not hinder the paving project, which is being designed by AECOM.
The scope of the proposed project includes potholing for locating main water lines, replace and lower service laterals, replace fire hydrants and fire hydrant laterals, replace fire service lines, replace isolating valves on the main line and on side streets.
Relocate the PRV station at the intersection of Riverside Avenue and Randall Ave into the sidewalk area just south of the southeast corner to enable safe operation & maintenance of the valves and avoid traffic-related concerns.
Veolia measured the depth of the valves at Randall-Riverside and in multiple other locations to approximate the depth of the water main. The average depth of the main water lines is 40 inches.
